Answer:
m∠AZB = 129°
Step-by-step explanation:
From the figure attached,
m∠AZB = m∠AZC + m∠CZB
It's given that measure of angle AZC = 90°
And measure of ∠CZB = 39°
Therefore, m∠AZB = 90° + 39°
= 129°

Erica has 1 5/8 cups of yogurt to make smoothies. Each smoothie uses 1/3 of a cup of yogurt. What is the maximum number of smoothies that Erica can make with the yogurt?
Answers
Answer:
4 smoothies.
Step-by-step explanation:
We divide 1/3 into 1 5/8 ( which is 13/8).
= 13/8 / 1/3
= 13/8 * 3
= 39/8
= 4 7/8
Maximum number = 4.

Answers
Answer:
y = ±5
x = ±6
Step-by-step explanation:
Here we have the system:
x^2 + y^2 = 61
x^2 - y^2 = 11
Notice that we have both variables squared, then we can define:
x^2 = X
y^2 = Y
And write our system as:
X + Y = 61
X - Y = 11
To solve this, the first step is to isolate one of the variables in one of the equations, i will isolate X in the second equation:
X = 11 + Y
Now we can replace this in the other equation to get:
(11 + Y) + Y = 61
Now we can solve this for Y
11 + 2*Y = 61
2*Y = 61 - 11 = 50
Y = 50/2 = 25
Y = 25
And remember that Y = y^2
then:
y^2 = 25
y = √25 = ±5
And using the equation: X = 11 + Y
X = 11 + 25 = 36
X = x^2 = √36 = ±6

Find the surface area
please show work
Answers
Answer:
Step-by-step explanation:
The pentagon faces are made up of five triangle each with 9 ft bases and 6.2 ft heights. And there are five rectangular sides of 9 by 5 feet. So the total surface area is
A=2*5*9*6.2/2+5*9*5
A=279+225
A=504 ft^2
Answer:
Formula: nl(b + h) it is derived as well
504 ft²
Step-by-step explanation:
Each vertical face is a rectangle.
Area of each face = length x breadth = lb
For n-sided polygon, area of vertical faces = n x lb = nlb
For horizontal faces:
Observe: you can actually divide that face in 5 right-angled triangle(two edge point & centre form right angled ∆). [For n-sided, that's n right angled ∆]
For 2 such faces, you have 2 x n times of area of 1 ∆.
Area of 2n∆ = 2n( ½ x h x base(length)) = nhl
Total area = area of horizontal surfaces + area of vertical surfaces
Total area = nlb + nhl = nl(b + h)
Total area = 5*9(5 + 6.2) = 504 ft²

carlos es un arquitecto y esta construyendo una casa si ha construido 3/7 de la casa le falta para acabarla es lo mismo que llegar a 7/7
Answers
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.
